EDF Energy IntroductionThe accident at the Fukushima Dai-ichi Nuclear Power Plant in Japan in March 2011 is one of only a few serious nuclear accidents in the history of the global nuclear industry. The focus of nuclear operators worldwide, and at EDF Energy, continues to be on safety as the nuclear industry emerged from this tragedy with an even stronger commitment to nuclear safety.
